Although you have the right gateway-setting in rc.conf, please check manually, if "net.inet.ip.forwarding" has a value of "1". Perhaps there's something later in rc.conf, in rc.conf.local or in rc.local that resets this variable to "0"? -volker -- Please don't cc me: I read the lists and don't need your message twice :-) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
